To be completely sure that your Ozempic® pen is empty, you can firstly check the dose counter. A reading of zero means that all the medication has been used.
But for complete assurance, try to dispense a dose. If your pen is indeed empty, you’ll hear a click sound instead of the usual feeling of pressure when delivering the medication. Also, the dose button will go in fully without any resistance, pointing to the pen being empty.
In addition, check your recorded dose history. The Ozempic® pen contains a pre-set number of doses and by comparing the used doses to the pen’s capacity, you can calculate whether or not the pen should be empty.
As a final measure, monitor your blood glucose levels frequently. A consistent rise in levels despite taking your medication regularly could indicate an empty pen.
Once the Ozempic® pen is empty, you’ll not be able to administer any more medication from it. Once you hear the click sound instead of feeling pressure when trying to deliver a dose, that means there is no medication left.
Even if relatively small quantities of medication appear to be present at the bottom of the reservoir, it is not advised that one try to use remaining medication. That’s because utilization may distort dosage accuracy as it’s impossible to measure the remaining amount accurately.
There’s also a risk of air being injected rather than the medication when the pen is nearing empty. Therefore, it’s not recommended to use the pen once it’s empty and a replacement should be sought immediately.
